Amar Kamat commented on HADOOP-4716:
------------------------------------
Also the following tweaks causes the test
_TestJobTrackerRestartWithLostTracker_ to pass consistently.
- _timeout_ : Set DEFAULT_READ_TIMEOUT = 3 sec (default = 3min) and
DEFAULT_CONNECT_TIMEOUT = 100 msecs (default = 3 secs) in {{ReduceTask.java}}.
- _freshness_ : clearing the _known output_ list in {{ReduceTask.java}} upon a
restart.
